The printing cylinder support unit for a printing machine according to the invention comprises a support frame, supporting means mounted on the support frame, and one of a plurality of positioning elements. The supporting means comprise displacement means and at least three support elements for each axial end of a printing cylinder, which support elements are designed each to interact with the positioning element at the location of a support point on the positioning element. The positioning element can be connected to one of a plurality of printing cylinders, the positions of the support points being related to the diameter of the printing cylinder in question. The displacement means are designed to move at least two of the support elements with respect to the support frame so as to receive positioning elements with different support point positions. The positioning element can be connected to the support elements in a rotationally fixed manner and comprises axle support means for accommodating a rotation axle of one of the printing cylinders.

Printing cylinder support unit, positioning element, printing cylinder provided with positioning element, printing machine provided with printing cylinder support unit, and its use

Printing cylinder supporting unit for a printing machine, with a supporting frame () aid supporting means mounted on said supporting frame for rotatably supporting one of several printing cylinders (), which are designed so that in the operating state they make contact along a contact line () with a substrate () that is to be printed, which printing cylinders () can have different diameters, the supporting means comprising at least three supporting bearings (), each of which interacts at the position of a bearing point with the hearing surface () of a bearing ring fixed concentrically on the printing cylinder (). The bearing points lie on a common circle with variable diameter. The supporting bearings are movable in such a way that the bearing points move along lines that have a fixed position relative to the supporting frame (), which lines intersect each other at a fixed reference point lying on the same common circle and in the operating state lying in a plane that is defined by the contact line () and the center point of the common circle.

Printing cylinder supporting unit, use of printing cylinder supporting unit, and printing machine provided with printing cylinder supporting unit

A printing-cylinder support unit has a support frame and supporting means which are mounted on the support frame and are designed to rotatably support one of a plurality of printing cylinders in a retaining position. The supporting means have at least three support elements for each axial end of a printing cylinder, which support elements are each designed to interact with a running surface of a bearing ring which is connected to the printing cylinder. One of the support elements has a support ring and suspension means, connecting the support ring to the support frame such that it can rotate about its axis. The support ring is provided on the inner side with a support-ring running surface, and the support ring is designed so that, in the retaining position, the support-ring running surface comes into contact with the running surface of the bearing ring.
